"I like to play golf. I like to cut my own grass," said Boehner, the top Republican in Congress.

"I do drink red wine. I smoke cigarettes. And I'm not giving that up to be president of the United States."

Boehner also told Leno he and Obama "get along fine" despite their political differences.

"But the country's gotten more partisan. So as a result the Congress has gotten more divided and there's less common ground," Boehner said.

Asked by Leno if the infighting in his own party was as bad as he had ever seen it, Boehner said, "Oh, no," before adding with a smile, 'Well, maybe it is. It's bad."

Since early 2011, Boehner has fought with conservative Tea Party Republicans in the House, mainly over deficit-reduction tactics. The government shutdown in October further frayed relations with right-wing groups.

"The funny thing about the so-called infighting is we agree on all the goals," said Boehner. "We think Obamacare is bad for the country. We think we shouldn't spend more than what we bring in. We think the president is ignoring the laws. It's all a fight over tactics. It's not over what our goals are."
